Description
Technical field
The utility model relates to contact network construction equipment, specifically the quick fixed card of a kind of contact net tower wagon.
Background technology
Contact net tower wagon is widely used in the construction of contact net top.In work progress, for what guarantee construction, normally carry out the safety with constructor, need to be fixed contact net tower wagon.Under prior art condition, be conventionally equipped with special constructor and contact net tower wagon carried out hand steered fixing.But practice shows, there are the following problems: one for this kind of contact net tower wagon fixing means, in hand steered fixation procedure, constructor need to stand on the below of contact net tower wagon all the time, and power tool above contact net tower wagon may fall down at any time, cause thus constructor easily to be injured by a crashing object, thus serious threat constructor's safety.Its two, in hand steered fixation procedure, at least need to be equipped with four (even six) special constructor and contact net tower wagon carried out hand steered fixing, cause thus the waste of manpower, thereby significantly increase construction cost.Based on this, be necessary to invent a kind of brand-new contact net tower wagon fastening devices, to solve existing contact net tower wagon fixing means, cause constructor easily to be injured and cause by a crashing object the problem of manpower waste.
Summary of the invention
The utility model causes constructor easily to be injured and cause by a crashing object the problem of manpower waste in order to solve existing contact net tower wagon fixing means, provides a kind of contact net tower wagon quick fixed card.
The utility model is to adopt following technical scheme to realize: the quick fixed card of contact net tower wagon, comprises clamping plate, left riser, right riser, del junction plate, bearing pin, left spring, right spring, tack claw; Wherein, left riser and right riser be the vertical middle part upper surface that is fixed on clamping plate all, and left riser and right riser position over against; The side, middle part of the side, middle part of left riser, right riser, the lower end side of del junction plate respectively offer about one the bearing pin installing hole connecting; Bearing pin is arranged in three bearing pin installing holes simultaneously; The rear upper end end face of del junction plate offers the break slot of up/down perforation; The rear side of the left cell wall of break slot, left riser respectively offers about one the left spring installing hole connecting; The rear side of the right cell wall of break slot, right riser respectively offers about one the right spring mounting hole connecting; The two ends of left spring are arranged in respectively in two left spring installing holes; The two ends of right spring are arranged in respectively in two right spring mounting holes; The front upper surface that is fixed on clamping plate is arranged in tack claw left and right.
During use, a quick fixed card of contact net tower wagon described in the utility model (amounting to two quick fixed cards of contact net tower wagon described in the utility model) is respectively installed on two chassis crossrails of contact net tower wagon.Installation process is as follows: the chassis crossrail of the front upper end of del junction plate and contact net tower wagon is welded and fixed.Then, constructor jams on the rear upper surface of clamping plate downwards, and upwards rotate around bearing pin the front portion that makes clamping plate, and it is following that the tack claw of clamping plate front upper surface turns to the upper ear of rail thus.Now, constructor stops jamming on the rear portion of clamping plate, and pulling back under elastic force effect of left spring and right spring, it is following that tack claw firmly hooks the upper ear of rail.Under the hook power effect of tack claw, contact net tower wagon is by firm fixing, and constructor can leave the below of contact net tower wagon.
Based on said process, compare with existing contact net tower wagon fixing means, the quick holding clamp of contact net tower wagon described in the utility model has the following advantages: one, in fixation procedure, constructor is without the below that stand on contact net tower wagon, even thereby the power tool above contact net tower wagon fall down, constructor can not injured by a crashing object yet, effectively prevented that thus constructor from being injured by a crashing object, thereby guaranteed constructor's safety.They are two years old, in fixation procedure, only need to be equipped with a special constructor and just can operate the quick fixed card of contact net tower wagon described in the utility model, with fixing of the net-fault tower wagon that achieves a butt joint, effectively avoid thus the waste of manpower, thereby significantly reduced construction cost.In sum, the structure of the quick fixed card of contact net tower wagon described in the utility model based on brand-new, efficiently solves existing contact net tower wagon fixing means and causes constructor easily to be injured and cause by a crashing object the problem of manpower waste.
Further, also comprise pivot; The front upper side of del junction plate offers the pivotal mounting hole that left and right connects; Pivot is arranged in pivotal mounting hole.During use, by pivot, the chassis crossrail of the front upper end of del junction plate and contact net tower wagon can be carried out to pivot joint and fix, further guarantee thus the fixing fixing of contact net tower wagon.
The utility model is rational in infrastructure, it is ingenious to design, and efficiently solves existing contact net tower wagon fixing means and causes constructor easily to be injured and cause by a crashing object the problem of manpower waste, is applicable to the construction of contact net top.
